An automatic golf ball lifting device has a remote control to turn the device ‘ON’ and ‘OFF’ from a far distance.

FIELD OF INVENTION

The present invention relates to an automatic golf ball lifting device.

BACKGROUND OF THE INVENTION

In playing golf, the players need to pick up the golf balls from the golf hole. This causes most players lots of ache and especially back pain. After repeating the action of picking up the golf ball, the back muscle and spine of the player quite often becomes injured. Thus, it would be advantageous to have any automatic device to help getting the golf ball up from the bottom of the hole. There has been so long time back since 1928 that Nao Uyel invented a hand operating caddy club device for picking up golf balls (U.S. Pat. No. 1,658,145). The device aids golf players to pick up golf balls from the ground without bending over and picking them up by hand which relieves the golf players of physical exertion necessary to pick up a golf ball from the ground. However, the device is not practical and too complicate such that it is almost ninety years now and none of such device is used. Neither there are any better devices for such purpose invented.

The present invention, the automatic golf lifting device therefore is designed to overcome all the problems cited and makes it possible for manufacturing and cost saving on production including making it practical when use.

SUMMARY OF THE INVENTION

An automatic golf ball lifting device capable of lifting a golf ball at the bottom of a golf hole up to ground level is described comprises a first cylinder having dimension of a standard golf hole, and a second shorter cylinder fit into said first cylinder where inside second cylinder there installed mechanisms for lifting the golf ball up to the ground level. The mechanisms for lifting the golf ball up in said second cylinder comprises: a golf ball plate: a circular plate to receive the golf ball; a load cell, installed underneath said golf ball plate at the uppermost end of a lifting set; a lifting set functions to move the golf ball plate up upon being actuated through a preset PCB, the lowest end of lifting set is connected to a ball screw set and the uppermost end of which is connected to the load cell; a ball screw set having screw which can turn clockwise or anticlockwise to allow lifting set to move up or down to a preset level; a motor functions to drive ball screw set through a bevel gear; a bevel gear rotates by motor and functions to turn the screw; a PCB electronically controls operation of all the components in the set; a battery supplies electrical power to motor. An automatic golf ball lifting device has a remote control set to turn the device ‘ON’ and ‘OFF’ from a far distance. A cover is used to prevent dust or any particles to fall into and interfere the function of the mechanisms inside the second cylinder where cover may be of rigid type or of any elastic type.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 shows the isometric view of an automatic golf ball lifting device 1 having an outer cylinder 11 made of stainless metal or any durable material. Cylinder 11 has the dimension of standard golf hole according to the R&A and the United States Golf Association and is placed as a golf hole. At the bottom of cylinder, there sealed with circular plate of the same material having holes of two different sizes in two rows surrounding a big hole at center which is mounted to a short cylinder 13. The holes surrounding the big center hole may be of any sizes and of any appropriate arrangement for the draining purposes. There are at least 7 fins on inner surface of cylinder 13 to help holding golf flag stick as shown in FIG. 2.

Inside cylinder 11, there is a second set 2 fits inside cylinder 11 with appropriate clearance. There are 3 main parts made up of set 2, i.e. the upper plate 21, the short cylinder 25, as shown in FIG. 2 and a bottom plate 29 as shown in FIG. 3. There are holes which also may be of any appropriate sizes and arrangement in the upper plate 21 and all over the plate 21 as shown in FIG. 2 to keep the golf ball in place when this plate is moving up.

As shown in FIG. 3, set 2 is composed of:

-   -   1. Golf ball plate 21: is a round plate made of metal or any         durable material having circular hole at center to fit to         cylinder 13 with appropriate clearance. Golf ball falls down         onto this plate 21 and is being lifted up back to ground level         as the mechanism is actuated.     -   2. Load cell 23: is installed underneath plate 21 at the         uppermost end of a lifting set 30.     -   3. Lifting set 30 made of durable material designed to be able         to change in length vertically within a predetermined time         interval, functions to move plate 21 up and down upon being         actuated through a preset PCB 54, where at lower end of set 30         is connected to a mechanism to cause change in length of the         set, preferably, a ball screw set 40 and the uppermost end         connected to load cell 23.     -   4. Ball screw set 40 having screw which turns clockwise or         anticlockwise to allow changing the length of set 30 vertically         to a preset level.     -   5. Motor 50 functions to drive ball screw set 40 through a bevel         gear 60.     -   6. Bevel gear 60 rotates by motor 50 and functions to turn the         screw of set 40.     -   7. PCB 54 electronically controls operation of all the         components in set 2.     -   8. Battery 56 supplies electrical power to motor 50.     -   9. Remote control set: is used to turn the device ‘ON’ and ‘OFF’         from a predetermined distance.

FIG. 4 shows how the mechanism of the lifting set 30 operates when a golf ball falls into the automatic golf lifting device 1, down onto plate 21 of set 2. Load cell is then actuated which allows lifting set 30 to start lifting plate 21 up to the ground level. The golf player can move the golf ball with no need to bend over. Once the golf ball is removed, the load cell senses the different weight and causes set 30 to become shortened to the lowermost position ready for the next cycle.

FIG. 5 shows a detachable golf ball receptacle 70 to be placed at the bottom of golf hole for manual use, where it is designed to have 14 fins all around with hole at center to hold golf flag

Cover 72 as in FIG. 6 is a thin plate made of stainless metal or any durable material used to cover the inner cylinder to prevent dust or small pieces of stone or any particles from falling down into the inner cylinder. The hole at the center allow it to fit into cylinder 13.

In addition, a bellow cover is used to cover the lifting set 30 and the ball screw set 40 to protect the components from dust or any particles which might fall down and interfere the functioning of the mechanisms.

Thus, to protect the components from dust or any particles which might fall down and interfere the functioning of the mechanisms, it is possible that either rigid type or elastic type of cover is used.
